9 JNI/ ENTOR WI NESSES CHARLES H. ANDERsoiv, 0F CINCINNATI, ,o1-no.'

To all 'whom it may concern.'k e ,Y l"'Be known that I, CHARLES 'HJ ANDER! soN, a citizen of the United` States, and ka resident of Cincinnati, in the county of Ham# ilton and State of Ohio,fhave invented certain new andusefulImprovements in Underframes for Cars; andI'do hereby declare the following t0V be aufulh'clear, andeX'ac't description of the invention,1,suclr {as will enable others skilled in the artflto'which it appertains to make and .use the same- My inventionY relates tornan improvement in car construction and particularly to parts of the underframe of electric or trolley cars, the .object beingto provide improved means for the attachment of the hangers which carry pipes, air tanks, and electrical apparatus now in universal useon the modern electric car, and it consists in the parts and combinationof parts as willhbe more fully4 described and pointed out in the claims.

In the accompanying drawings, Figure lis a view in transverse section through a part of a car floor showing my improvement. Fig. 2 is a view in transverse section through the cross-sill showing the manner of securing a pipe thereto. Fig. 3 is a view in elevation of a part of the sill and showing the pipe hanger and pipe. Fig. 4 is a view similar to Fig. 2, showing the manner of securing the Hoor to the sill, and Fig. 5 is a view in longitudinal section through a part of the car floor showing a hanger or carrier secured to two sills.

All electric cars carry considerable equipment, such as pipes, tanks and electrical apparatus, and with the cars as now constructed, it is necessary to first locate the various pipes and parts to be mounted on the underframe and then drill holes at the proper points in the steel work for the attachment of the supporting hangers or bolts.

I attach all the parts to the cross-sills 1 of the underframe, each crosssillrbeing of box form with an open slot 2 extending throughout its length, or at leastthrough such parts thereof as are available for the attachment of supporting hangers. The metal at the side edges of the slot is turned back or doubled over as at 3, as kclearly shown in Fig. 2, so as to increase the area of the metal and make it balance the-[topf chord, and each is preferably provided UNDERFRAME ynon: i GARS.

its sides with holes`4,"fwhich` lighten up the sills' and alsoprovide `for access to the in# terior `thereof forrjthe manipulation of the boltswhich securethe hangers iny place.

Y In the drawings I have' shown hangers for carrying pipes i5, which may be` air, steam, or water pipes, or conduits forl electric wires;A hangers ,forcarrying' a tank ,6 and in Fig. 5 aA hanger carriedby,twocross# sills. vIn eachinstance the securing bolts are passed intof the crosssills ,throughvr the openings4 'and' throughk theflat washers .7?,

in the sill and singley washer?, may

' form the seat for one orimore bolts:'secur-y ing a hanger 9, and as vthe washer isint'e'r#l ylocked with the sill, -it prevents anylateral v.spreading of theV latter and also adds to its strength. l

In Fig. 5 I have `shown a hanger 6a supported at its ends by bolts carried by two adjacent cross-sills, with a carrying frame l0 bolted to the hanger 6a. Byslotting the hanger 6, or providing it with a series of holes for the bolts 11, the mounting is l'practically universal, that is to say, the hanger 6a can be located at anyfpoint throughout the length of the cross-sills and the carrying frame 10 at any point throughout the length of the hanger 6a. VIf. the floor boards 'or plates 12, be secured to the cross-sills 1 by screw bolts, as

shown in Fig. 4, the nuts for securing kthe bolts, will be applied through the openings or through the slots 4 in the sills.

With this improvement, the necessity for exact location will be eliminated, andthe cost of drawings and the preliminary workk of locating the parts saved.

1. In a car underframe, the combination of a hollow metal cross-sill having a longi tudinal slot extending lengthwise its lower member, a bolt passing through said slot and supported solely on the metal of the sill at the sides of the slot, and a hanger secured to the bolt below the sill. A

2. In a car underirarne, vthe combination of a box form cross-sill having a slot in its lower member extending lengthwise the s ill, the edge of metal at the two sidesl of the slot being turned over onto itself, a bolt passing from the inside of the sill through i the slot, and a hanger secured to said bolt.

5. In a car underframe, the combination of abox rform cross-sill having a slot in its lower member extending lengthwise the sill,

a washer within the sill and'bridging the slot, a vbolt passing from the inside of the sill through said washer and slot, and a hanger secured to the bolt.

In a carunderframe, the combination of a box form cross-sill having a slot in its lowermernber extending lengthwise the sill,

the edges of the metal at both sides of the slot being bent over onto itself, washer Copies ofthis patent inajibeobtainedpfor supported on said bent edges, a bolt passing from the inside of the sill through the washer and slot, and a hanger secured to the bolt.

5.
